The identification of host and virus proteins that modulate the induction of immunological memory is important for improving virus-based vaccine design and efficacy. In viruses, the expression of BTB-BACK Kelch-like (BBK) proteins is restricted to poxviruses and conserved within them, indicating the importance of these proteins for these medically important viruses. Using vaccinia virus (VACV), the smallpox vaccine, we report that the VACV BBK protein A55 dysregulates NF-\u03baB signaling by disrupting the p65-importin interaction, thus preventing NF-\u03baB translocation and blocking NF-\u03baB-dependent gene transcription. Infection with VACV lacking A55 induces increased VACV-specific CD8\n            <jats:sup>+<\/jats:sup>\n            T-cell memory and better protection against VACV challenge.
